Log Message:
Suppress spurious timeouts and avoid wedging in OACTIVE state:

        1 Set or clear OACTIVE as transmit buffers are depleted or
        replenished, respectively.  Do not use 802.11 acknowledgements
        as a criteria for clearing OACTIVE.

        2 Let each transmit queue count down to timeout independently,
        and get rid of the shared countdown (sc_tx_timer).  When
        we add a packet to a transmit queue, restart the queue's
        countdown.  Stop a transmit queue's countdown when the
        queue empties.
